Sentence examples for model for speciation from inspiring English sources
The simplest continuous-time model for speciation in phylogenetic trees is the Yule process, in which new species are "born" from existing lineages at a constant rate.
The evolutionary history of the D. simulans complex has been debated (e.g., [2], [31]), meriting attention at least in part because of the importance of the complex as a model for speciation.
Thus, the sequences described here provide initial insight into male and female post-mating molecular interactions in a model for speciation.
Extensive genetic resources and the fertility of hybrid females have made D. mauritiana, in particular, an important model for speciation genetics.
At any rate, a model for speciation in ducks must be able to explain the observed pattern of genetic and morphological differentiation in spite of the high degree horizontal gene exchange.
The involvement of the sex chromosomes in TRD in populations derived from multiple mouse subspecies is not unexpected (Payseur et al. 2005; Mihola et al. 2009; White et al. 2011) and may provide an elegant model for speciation.
The Fracture-Matrix Transport (FMT) code couples saturated porous medium advection and diffusion with mechanistic chemical models for speciation and interphase reactions.
Even the proposed competing models of geographic speciation in the Indo-Pacific remain contentious and generally involve different facets of the classic dispersal or vicariance models for speciation.
The anther-smut fungi (genus Microbotryum) serve as models for speciation in the face of sympatry, and previous studies have tested for but not detected assortative mating.
DOI: http://dx.doi.org/10.7554/eLife.01751.004 To characterize the structures and functions of sex-specific TAGs, we focused on desert-adapted drosophilids from the D. repleta group, Drosophila arizonae and Drosophila mojavensis, two well-characterized models for speciation, reproductive isolation, and ecological studies (Ruiz et al., 1990; Markow, 1996; Etges and Jackson, 2001).
Not many investigations of phenotypic plasticity in model systems for speciation research, such as cichlid fishes, have been attempted (but see [ 29- 33]).
